Zusammenfassung:	A device for powder based additive material manufacturing of dental appliances. The device has a recoater (10) for providing a powder layer to a build area. The recoater (10) has a slide (11) and is adapted for dispensing of the powder to the build area. The recoater (10) has further at least two powder supplies for individually supplying a first and a second powder on the slide (11) and a powder transport section in which the first and second powder are brought in touch with each other for at least partially merging. The invention is advantageous in that it allows providing dental blanks having color gradients in all three dimensions.
